How many people have compared their OSI weather station RH% values against other surrounding CWOP or NWS values in an effort to learn how "close/far" their OSI values are from reality?
I ask, because it's looking as though the TEMP's are OK (±1ºF), but the RH% and DEWPOINT TEMP (Tdp) values are obviously not OK. The Tdp values around me (3 other CWOP within 5 miles) seem to be basically "flat" with minor fluctuations (not counting big WX changes), while MY Tdp values are mirroring the TEMP shape both day and night...which (to me) indicates the RH% values are wrong, because Tdp is merely a derived (calculated) function of TEMP and RH%.
Anybody else notice similar "idiosynchracies" in their OSI weather station outdoor sensor (THGN801) values, especially RH% and Tdp? If yes, what have you done to compensate for their error(s)? Any suggestions or ideas? I've already written OSI asking about "better" accuracy, but I'm not holding my breath.

I have a LaCrosse, Davis and OS all on the same pole. They all read pretty close (most of the time) (except that the Lacrosse only goes up to 87% RH).
